Safety standards that can survive contact with real products.
SafePrint is a neutral, pre-competitive effort focused on practical 3D-printer safety standards, certification, and compliance infrastructure. Calynx leads implementation and systems architecture across the program’s technical trust boundaries.
-
01
Policy into architecture
Translate public-safety goals into testable technical requirements and system boundaries.
-
02
OEM-realistic implementation
Pressure-test assumptions across printers, slicers, firmware, services, and update models.
-
03
Privacy-preserving trust
Design for signed authorization, local verification, auditability, and bounded data exposure.
Issues the keys, not the printer vendor.
Registry keys: private to the CPAM; public to the printer.
Arranges the models.
Certified Print Authorization Module
Runs with the slicer, locally or in the cloud. Two inputs in, only authorized g-code out.
Verifies the signature and prints only if authorized.
Inside the CPAM: four checks, in order
-
1Correspondence
The g-code reconstructs exactly the parts you submitted.
-
2No hidden parts
Real parts are watertight; supports are not, so anything hidden shows.
-
3No regulated geometry
Each part is screened against the signature list of regulated components.
-
4Authorize
On pass, the g-code is cryptographically signed for the printer.
Working with state and consortium stakeholders while inviting OEM input before technical requirements harden.
